EDWARD B. STARR AND MOKINLEY STOCKTON, OF LOMPC, CALIFORNIA.

DISINTEGRATOR.

Application filed July 25, 1921.

To all `whom/1f may concern.'

Be it known that we, EDWARD B. STARR and MCKINLEY S'rooKToN, citizens of the United States, residing at Lompoc, in the county of Santa Barbara and State of California, have invented a new and useful Disintegrator, of which the following is a specifcation.

This invention relates to machines for disintegrating, or reducing rock, or other material, to a linely divided condition. The machine is especially adapted to disintegrating materials of cellular construction and of exceptional lightness in weight, such material being adapted to be removed from the machine by a blower, or like device.

The main object of the invention is to provide a disintegrator of simple construction which will be effective in reducing such rock, or other material, to a granular or finely divided condition without destroying the cellular or porous structure of such material.

A further object of the invention is to provide means for adjusting or controlling the operation of the machine in breaking up the material and in removing the fines therefrom.

Another object of the invention is to provide means for trapping and removing flint1 metal, or other hard and heavy material which may enter the machine.

The accompanying drawings illustrate an embodiment of our invention, and referring thereto:

Fig. 1 is a plan view of the machine partly broken away to show the interior construction;

' Fig. 2 is a partly broken side elevation 40 thereof;

Fig. 3 is a perspective view of one of the impact plates, showing the means for adjustment thereof;

Fig. 4 is a perspective of one of the clamping disks for the breaker arms;

Fig. 5 is 'a perspective of one of the breaker arms;

Fig. 6 is a perspective of the rotor or rotary member of the machine.

Fig. 7 is a side elevation of the disintegrator, and of a suction fan connected thereto.

The machine comprises a casing 1 of Serial No. 487,347.

metal, or other suitable material, provided with bearings 2 in which is rotatably mounted a shaft 3, which is connected to or provided with suitable driving means for rotating the same at high velocity, said shaft 3 carrying a plurality of breaker arms 4, preferably extending radially with respect to the shaft. The casing 1 is provided with a mouth or feed opening 5 in the upper portion thereof and to one side of the axis of the shaft 3, said feed opening being permanently open or unobstructed. so as to permit the material to be fed freely into the machine. Below said opening the casing is provided with a vertical impact plate 6 of suitable hard metal extending in the path of the material as it is projected or thrown by the operation of the breaker arms, as hereinafter described. Said impact plate is preferably corrugated as shown at 16. The bottom portion of the casing, below said feed opening and below the plate G, is flat and extends horizontally from the lower' end of the curved portion of the casing hereinafter referred to, and directly adjacent to this bottom portion the casing is provided with a lateral extension to form a trap or pocket 7 for receiving flint. metal, or other hard material` said pocket having a lateral opening 8 normally closed by a plate 9 which may be retained in place by a bar 1() supported by hooks 11. The side of the casing 1 opposite to the impact plate G is preferably curved, for example, concentrically with the shaft 3, as indicated at 12, and is provided with an outlet opening 13 communicating with an exhaust pipe 14, which leads to any suitable blower or exhaust device, indicated at 18 in Fig. 7 for producing sufficient suction at the outlet opening 13 to draw off the fines or disintegrated material. The outlet opening 13 extends transversely to the direction of circumferential motion of the rotor, for example, as shown, the said outlet may extend horizontally outward from the circumferential portion of the casing and may be located somewhat above the axis ofthe rotor so that the material thrown off by the rotor in a tangential direction with reference to the motion of the rotor is caused to escape from the casing in a direction which has a component transverse to the circumi ferential direction of rotation and a component reverse tosuch direction of rotation. In the portion of the casing adjacent to the outlet opening and'between thepath of the outer ends of the breaker arms and the outlet opening, so as to be in the path of the material projected by the breaker arms are arranged a plurality of impactand deflector plates, vanes, or baiiles 15, each consisting of a .plate of suit-able netal,'or other material,y extending from side to side ofthe casing and provided with end vflanges 17 j Vbolted to the vertical sides 19 of the casing. In order to enable angular adjustment of Vthese vanes they may be' arranged to pivot on bolts 20 and be fastened in any dej sired angular position by bolts 21 engaging Y AVin,l slots `22 in the sides 19 of the casing. The

vanes 15 are preferably arranged in a circular a-rc so as to form discharge slots 23 'between successive vanes; and the width of Vthese slots, as well as the angle of presenta- .tionof .the vanes, may be determined by adjustment of the fastening'means 21 aforesaid. These plates or vanes are so positioned y that inall adjustments of same they extend obliquely outward in a rearward direction,

l u with reference to the circumferential motion with the plates are deflected rearwardly as they pass between the plates tothe outlet, with the result that only the Vfiner and tion. Vanes* or plates 15may 26. It will be un number of such breaker arms may be used,`

of the outer ends of the breaker arms, so that the currents of air passing in-contact lighter material lis drawn with the air currents' to the outlet, andthecoarser material, impingingv on the plates, is carried forward by the momentum thereof and is retained within the machine for furtherdisintegrahave stiifening or reinforcing flanges v30'.

Therotor or rotary member is vpreferably Y constructed in such'mannerthat the breaker transverse or angularly disposed Vrelatively Y to leach other, the dowal pins 25 aforesaid 'projecting'from the bottom of vthese grooves in such 'manner that when the parts are assembled each breaker. arm 4 will enter and be held ino posing grooves 29 of adj aeent disks 26 and a-trnate breaker arms will extend transversely or at right angles to one another.

by reason of the transverse arrangement of the grooves 29 on tpposite sides of the d isks erstood that any deslred and they may be disposed in any angular positions with respect to lone another and to the shaft 3, and may be either radial to shaft 3, or otherwise arranged. The disks 26 are held in assembled relation by bolts 37 passing through perforations 32 in said disks.

-By loosening said bolts any two adjacent disks may be separated sufiiciently to enable an' intervening breaker arm 4 to be slipped out and replaced by another arm, without disturbing the other parts.

The operation is as follows:

The rock, or other-material to be disintegrated, for example, diatomaceous earth, is introduced into the feed opening 5 by any suitable feeding means, and, the shaft 3 being operated so as lto be rotated rapidly in the direction of the arrow in Fig. 2, the breaker arms 4 strike the material as it is descending in the casing 1 and also continues to strike and beat the material as it laccumulates in the bottom of thelv casing, so as to throw or project the material circumferentially in the directionof motion of the arms 4, and to cause such material to impinge on the impact plate Gand on the vanes 15, whereby the material is broken up or disintegrated by impact of the arms 4 and by impact of the material on the stationary members 6 and 15. At the same time a draft or current of air is maintained through the casing 1 from the feed opening 5 to the outlet 13, by suitable suction means connected to outlet pipe 14, so that the. fine disinte grated material is drawn through passages 23 between the vanes 15 and out at said outlet opening. By means ef the change in direction of the material in escaping at said outlet openings from a forward circumferential directiontoa rearward or reverse direction,` with reference to the direction of rotation, we ensure 'that only the finer particles will so escape, the coarser or heavier ieces, by means of the tangential momentum imparted to them, yby the rotary breaker means, being carried past the, outlet opening without beingI drawn out by the suction. The material is fed into the casing in a direction tangential to the movement of the breaker arms 4, so as to fall directly into the path of such arms-and to readily take up the circumferential motion. The angle at which the material projected by the breaker" arms strikesthe vanes 15 and the effect., of

the resulting impact may be varied byv adjusting said vanes asf above described, and such adjustment also provides for varying the exhaust or discharge openings 23 between l the vanes.-

In the above described o eration only the finer material is drawn off y the suction at l .means Any hard and diicultly breakable bodies, such as pieces of flint, or of metal, Will lfall, or be thrown. directly into the pocket 7 and remain out of the path of the breaker arms and may be removed from time to time by removing the plate 9.

'hat we claim is:

1. A disintegrator comprising a casing provided with a feed opening in its top, and with an outlet opening extendimgr outwardly from a circumferential portion of the casing, a shaft mounted to rotate within the casing and provided with breaker arms, suction means connected to said outlet to draw air Jfrom the casing through the outlet, an impact plate within the casing and below said opening` and a plurality of impact and fleflector plates mounted within the casing and between the path of the outer ends of the breaker arms and the outlet, said plates being' inclined rearwardly and outwardly with reference to the circumferential motion of the outer ends of the breaker arms, so as to deflect rearwardly the currents of air passing in contact with and between said plates to said outlet, whereby only the finer material is carried with such air to said outlet and the coarser material is retained within the easing for further disintegration.

2. A construction as set forth in claim 1, in which said plates are angularlyadjustable, to vary the angle of impact and the size of the openings between them.

3. A disintegrator comprising a casing, a shaft mounted to rotate Within said casing' and provided with breaker arms, said casing having a feed opening in its top, a vertical portion below said feed opening, a portion opposite said vertical portion, concentric with said shaft, an outlet extending from said concentric portion, a bottom portion extending horizontally from the lower end of said concentric port-ion, and a lateral extension of such horizontal bottom portion formingr a trap for hard material, a vertical impact plate on said vertical portion of the casing, and delector plates extending Within the casing between the path of movement of the outer ends of the breaker arms and said outlet.

In testimony whereof we have hereunto subscribed our names this 14th day of July,

EDWARD B. STARR. MGKIN LEY STOCKTON.
